This tutorial shows you how to list your images in a csv file and resize every image in that list automatically.
WHOOO! AUTOMATION! 馃帀
ImageMagick is a free and open-source software suite for displaying, converting, and editing raster image and vector image files.聽
find /home/project/ -name "*.jpg" -print| while read LINE; do echo "$LINE" ; done > list_with_images.csv# define the settings
export MAGICK_THREAD_LIMIT=1;
export MAGICK_THROTTLE_LIMIT=100;
export MAGICK_MEMORY_LIMIT=500mb;
start=0;
end=$(cat $1 | wc -l)
loop through every line of the given file
while read file; do
echo "[x] Optimizing $file"
echo $(($end-$((++start)))) elements remaining of $end
replace="_optimized.jpg"
targetFile="${file/.jpg/_optimized.jpg}"
echo "Optimizing $file to $targetFile"
convert "$file" -resize 1920 "$targetFile"
# let the CPU rest for 10 sec
sleep 10
done < $1
You can edit the script to your liking. it doesn't replace the original image, but creates a new one with a postfix of "_optimized".
Original: test_image.jpg
Optimized: test_image_optimized.jpg
